NORMAN, Okla. -- Top-seeded Oklahoma punched its ticket to the 2013 Women's College World Series on Saturday in the same manner they had won games all season: power at the plate and strong pitching in the circle.

Senior Keilani Ricketts threw her 16th shutout of the season and sophomore Shelby Pendley belted two home runs as the Sooners (52-4) rolled to an 8-0, five-inning win against 16th-seeded Texas A&M (42-18).

OU advances to the World Series for the third year in a row and eighth time in program history. In getting there, the Sooners have outscored teams 59-8 so far in the postseason, including four wins via run-rule.

Ricketts secured the win and improved her record to 31-1. She struck out seven, allowed just three hits and didn't walk a batter. In the two-game sweep, Ricketts was 2-0 with a 1.27 earned run average, struck out 20 and walked just one batter in 11.0 innings of work.

The win was No. 129 of Ricketts' career, tying Hofstra's Olivia Galati for 10th most in NCAA Division I history.

Oklahoma got on the board in the first inning thanks to Pendley's first home run of the day, a solo shot to right center.

Pendley did it again in the third inning, blasting her second shot of the day.

Sophomore Lauren Chamberlain reached on a one-out single to center field. Fellow sophomore Georgia Casey then walked before Pendley launched a long three-run blast to right field.

It was her eighth career multi-home run game and her fifth this season. She has recorded 41 career home runs, 22 of which have come this season.

Oklahoma then broke the game open with a two-out rally in the fourth inning, tacking on four more runs. The team has now scored 200 of its 444 runs with two outs this season, or 45 percent.

After a groundout and lineout, senior Brianna Turang kept the inning alive with a single up the middle. Chamberlain walked to extend her school record to 59 this season. Casey was hit by a pitch to fill the bases before Pendley drew a walk on a full-count to make it 5-0.

Ricketts tacked on two more runs as she pulled an RBI double down the line, while junior Brittany Williams singled through the right side to score Chamberlain and bring in the game's eighth run.
